At least 67 people have died in clashes since October when an 18-party opposition alliance led by Bangladesh Nationalist Party launched a wave of protests calling on Prime Minister Sheikh Hasina to resign before the polls and set up a non-party interim government.
The BNP, led by Hasina's bitter rival Khaleda Zia, is boycotting the polls as it has not fielded any candidates and former President H M Ershad's Jatiya Party, a former ally of the Hasina-led Awami League, has announced it will also not participate in the elections.
